Abstract

The invention provides a photocatalytic self-cleaning non-woven fabric, a preparation method and a mask prepared from the photocatalytic self-cleaning non-woven fabric, the non-woven fabric comprisesa non-woven fabric base material, and the surface of the non-woven fabric base material is coated with a TiO2 / SiO2 nanoparticle coating; the non-woven fabric base material is prepared from the following components in parts by weight: 70-80 parts of polypropylene, 10-20 parts of sodium p-styrenesulfonate, 10-20 parts of a silane coupling agent, 2-10 parts of aniline, 1-5 parts of nano titanium dioxide and 1-5 parts of bamboo charcoal fibers. The surface of the non-woven fabric base material is coated with the TiO2 / SiO2 nanoparticle coating, so that the non-woven fabric base material is endowedwith dual effects of photocatalysis and self-cleaning, not only has low refractive index and good thermal stability and mechanical stability of SiO2, but also has good photocatalytic performance and hydrophilic performance of TiO2, and the self-cleaning efficiency of the mask under different illumination conditions is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of masks, and relates to a nonwoven fabric, a preparation method and a mask prepared by using the same, in particular to a photocatalytic self-cleaning nonwoven fabric, a preparation method and a mask prepared by using the same. Background technique [0002] Since entering the 21st century, human industrial civilization has developed rapidly, and the environmental pollution problems caused by it have become increasingly serious. Today, with the increasing prosperity and development of the economy, the problem of environmental pollution has become a focus problem that directly threatens the survival of human beings and needs to be solved urgently. Moreover, with the development of the world economy, personnel exchanges are unprecedentedly frequent, and the possibility of various diseases, especially infectious diseases, is increasing day by day. Some sudden diseases have large-scale outbreaks from time to tim...
